We have installed a PCI-GPIB card on a Windows XP computer. The card is found and a device (DMM at addr 5) can be read on XP level. However our DOS application (produced under LabWin/DOS) does not find the card nor can it read the device. Where can be an error?
Your error is that DOS cannot use a 32-bit Windows driver (DOS is a 16 bit OS). You would need to also install a DOS driver for the card but according to the information here, a DOS driver is not available for the PCI-GPIB. You will need to pick a different GPIB card from the list for which a DOS driver exists.
